CBIZ was looking for a way out of its predicament months before Grant Thornton called, and longer still before an activist investor wrote to tell the board what to do. In the end, CBIZ took $55 per share from Grant Thornton, but only after rejecting three lower offers from the firm.

Marcum made CBIZ bigger almost overnight. It also quadrupled the debt, more than tripled interest expense, and left executives figuring their best option was Grant Thornton’s $5-billion buyout offer.

CBIZ entered 2026 looking like one of accounting’s great consolidators. Revenue had risen 52.1% in 2025 to $2.758 billion, and net income had increased 181.3% to $115.4 million.
And yet, by July 28, the company is ready to take $55 per share, better than the $46.70 the day before, but less than the $88.65 peak last year.
Ryan Bunn, the activist shareholder at Reference Equity, which had been pressing the company since mid-June to raise equity and keep buying firms, says the decision “feels like capitulation.”

“The elimination of the CPA license altogether – or having a license so degraded and devalued that anybody could put those letters behind their name – I don’t know what terrifies me more,” Weir tells Jean Caragher in this episode of Gear Up for Growth.
For Marcum partners, it’s complicated.

Same deal. Same $55 a share, cash, on the table for every CBIZ shareholder. Four completely different outcomes, depending on when you bought in.
